Abstract

A molding container including a lid that can be smoothly pulled out of a molded frozen dessert with no damage to the molded frozen dessert is provided. A frozen dessert container assembling method of assembling: a main body capable of containing a frozen dessert; a first lid including a first peripheral edge portion and a protrusion that forms an inner space on the inner radius side of the first peripheral edge portion; and a second lid including a second peripheral edge portion and a cover portion is provided. This method includes the steps of: feeding the main body; causing the protrusion of the first lid to be contained in the main body and fitting the first peripheral edge portion and an opening of the main body to each other; and covering the inner space of the first lid with the cover portion of the second lid and fitting the first peripheral edge portion and the second peripheral edge portion to each other.

The invention claimed is: 
     
       1. A method for assembling a frozen dessert container comprising a main body having an opening defined by an inner surface capable of containing a frozen dessert, a first lid having a first peripheral edge portion and a protrusion for forming a hollow portion within the frozen dessert, the protrusion having an inner space on an inner radius side of the first peripheral edge portion, and a second lid having a second peripheral edge portion and a cover portion, the method comprising the steps of:
 feeding the main body to an assembling line; 
 placing the first lid on top of the main body on the assembling line, so that the protrusion of the first lid is surrounded by the inner surface of the main body and is located within the main body, and the first peripheral edge portion of the first lid is attached to the opening of the main body such that the first lid is detachable from the main body by a first force; and 
 attaching the second lid on top of the first lid on the assembling line, so that the inner space of the protrusion of the first lid is covered by the cover portion of the second lid, and the second peripheral edge portion of the second lid is attached to the first peripheral edge portion of the first lid such that the second lid is detachable from the first lid by a second force, wherein 
 the second force is larger than the first force so that the first lid is detachable from the main body more easily than the second lid is detachable from the first lid, and the first lid is detachable from the main body without detaching the second lid from the first lid. 
 
     
     
       2. The method for assembling a frozen dessert container according to  claim 1 , wherein
 the first peripheral edge portion is attached to the opening of the main body by a first fit structure, 
 the second peripheral edge portion of the second lid is attached to the first peripheral edge portion of the first lid by a second fit structure, and 
 the first fit structure between the first peripheral edge portion and the opening of the main body is separable more easily than the second fit structure between the first peripheral edge portion and the second peripheral edge portion. 
 
     
     
       3. The method for assembling a frozen dessert container according to  claim 1 , wherein the protrusion of the first lid has an inverted conical shape. 
     
     
       4. The method for assembling a frozen dessert container according to  claim 1 , further comprising a step of feeding a frozen dessert into the main body after feeding the main body to the assembling line and before placing the first lid on top of the main body. 
     
     
       5. A method for assembling a frozen dessert container comprising a main body having an opening defined by an inner surface capable of containing a frozen dessert, a first lid having a first peripheral edge portion and a protrusion for forming a hollow portion within the frozen dessert the protrusion having an inner space on an inner radius side of the first peripheral edge portion, and a second lid having a second peripheral edge portion and a cover portion, the method comprising the steps of:
 feeding the main body to an assembling line; 
 placing the first lid on top of the main body on the assembling line, so that the protrusion of the first lid is surrounded by the inner surface of the main body and is located within the main body, and the first peripheral edge portion of the first lid is detachably attached to the opening of the main body; and 
 attaching the second lid on top of the first lid on the assembling line, so that the inner space of the protrusion of the first lid is covered by the cover portion of the second lid, and the second peripheral edge portion of the second lid is detachably attached to the first peripheral edge portion of the first lid, wherein 
 the second lid is attached to the first peripheral edge portion of the first lid by a fit structure or a sealing, so that the second lid is more firmly attached to the first lid, and the first lid can be detached from the main body more easily than the second lid is detached from the first lid, without detaching the second lid from the first lid. 
 
     
     
       6. The method for assembling a frozen dessert container according to  claim 5 , wherein the protrusion of the first lid has an inverted conical shape. 
     
     
       7. The method for assembling a frozen dessert container according to  claim 5 , further comprising a step of feeding a frozen dessert into the main body after feeding the main body to an assembling line and before placing the first lid on top of the main body.
